ShadowNav: Crater-Based Localization for Nighttime and Permanently Shadowed Region Lunar Navigation
Abhishek Cauligi, R. Michael Swan, Masahiro Ono +4
There has been an increase in interest in missions that drive significantly longer distances per day than what has currently been performed. Further, some of these proposed mission…
LunarNav: Crater-based Localization for Long-range Autonomous Lunar Rover Navigation
Shreyansh Daftry, Zhanlin Chen, Yang Cheng +7
The Artemis program requires robotic and crewed lunar rovers for resource prospecting and exploitation, construction and maintenance of facilities, and human exploration. These rov…
Lunar Rover Localization Using Craters as Landmarks
Larry Matthies, Shreyansh Daftry, Scott Tepsuporn +5
Onboard localization capabilities for planetary rovers to date have used relative navigation, by integrating combinations of wheel odometry, visual odometry, and inertial measureme…
Mid-Air Helicopter Delivery at Mars Using a Jetpack
Jeff Delaune, Jacob Izraelevitz, Samuel Sirlin +32
Mid-Air Helicopter Delivery (MAHD) is a new Entry, Descent and Landing (EDL) architecture to enable in situ mobility for Mars science at lower cost than previous missions. It uses…
Multi-Resolution Elevation Mapping and Safe Landing Site Detection with Applications to Planetary Rotorcraft
Pascal Schoppmann, Pedro F. Proença, Jeff Delaune +5
In this paper, we propose a resource-efficient approach to provide an autonomous UAV with an on-board perception method to detect safe, hazard-free landing sites during flights ove…
Online Photometric Calibration of Automatic Gain Thermal Infrared Cameras
Manash Pratim Das, Larry Matthies, Shreyansh Daftry
Thermal infrared cameras are increasingly being used in various applications such as robot vision, industrial inspection and medical imaging, thanks to their improved resolution an…
Online Self-supervised Scene Segmentation for Micro Aerial Vehicles
Shreyansh Daftry, Yashasvi Agrawal, Larry Matthies
Recently, there have been numerous advances in the development of payload and power constrained lightweight Micro Aerial Vehicles (MAVs). As these robots aspire for high-speed auto…
Cubic Range Error Model for Stereo Vision with Illuminators
Marius Huber, Timo Hinzmann, Roland Siegwart +1
Use of low-cost depth sensors, such as a stereo camera setup with illuminators, is of particular interest for numerous applications ranging from robotics and transportation to mixe…
Multi-Type Activity Recognition in Robot-Centric Scenarios
Ilaria Gori, J. K. Aggarwal, Larry Matthies +1
Activity recognition is very useful in scenarios where robots interact with, monitor or assist humans. In the past years many types of activities -- single actions, two persons int…
Pooled Motion Features for First-Person Videos
M. S. Ryoo, Brandon Rothrock, Larry Matthies
In this paper, we present a new feature representation for first-person videos. In first-person video understanding (e.g., activity recognition), it is very important to capture bo…
Early Recognition of Human Activities from First-Person Videos Using Onset Representations
M. S. Ryoo, Thomas J. Fuchs, Lu Xia +2
In this paper, we propose a methodology for early recognition of human activities from videos taken with a first-person viewpoint. Early recognition, which is also known as activit…
